Service and End Selection

5.A.1.
Any fair method shall be used to determine which player or team has first choice of end, serve, receive, or defer (e.g., a 1 or 2 written on the back of the score sheet, flipping a coin). If the winner chooses to serve or receive first, the loser chooses the starting end. If the winner chooses the starting end, the loser chooses to serve or receive. Once a selection has been made, it cannot be changed.

5.A.2.
In doubles, teams may change the starting server between games and should notify the referee. In non-officiated matches, the team should notify the opponents if there was a starting server change. The starting server for the game is the player wearing the starting server form of identification. There is no fault or penalty for failure to make the notifications. Once a game has started, if the referee notices a starting server has changed, the referee will annotate the scoresheet accordingly, after the rally has completed.

5.A.3.
In doubles, the starting servers must visibly wear the form of identification determined by the Tournament Director.
